CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 265,393, dated October 3, 1882,

Application filed March 14, 1882.

v meut in Oar-Couplings, of which the following is a full, clear, and exact description.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a front elevation of acar to which our improvement has been applied. Fig. 2 is a side elevation of the same, partly in section. Fig. 3 is a plan view of the same, partly in section. Fig. 4 is a sectional side elevation of the draw-head. Fig. 5 is a perspective view of the guard.

The object of this invention is to facilitate the coupling and uncoupling of cars.

The invention consists in a car-coupling constructed With a draw-head, a hinged couplingpin, a hinging cross-pin having a crank-arm upon its end, a chain attached to the crankarm, a rod having crank-arms for raising the coupling pin and looking it when raised, a guard to protect the hinging cross-pin, and a cap-plate toprevent rain and sleet from entering the draw-head; also, in the combination, with the draw-head, the hinged couplingpin, and the hingiug cross-pin having a crankarm upon its end, of the connecting-chain and the rod having crank-arms upon its ends, whereby the coupling-pin can be readily raised and can be locked in a raised position and, also, in the combination, with the draw-head, thehinged coupling-pin, and the hiugiug crosspin, of the guard and its bolt, whereby the said cross-pin will be protected from the entering link, as will be hereinafter fully described.

A represents a car-body. B is the draw-bar, and U is the draw-head.

D is the coupling-pin, which is placed with in the draw-head (J, and is made of such a length that its ends may enter holes in the upper and lower sides of the said draw-head, and thus have a firm support when sustaining the draft-strain. In the upper end of the couplingpin D is formed a square hole to receive the square middle part of the cross-pin E, which (N0 model.)

passes through holes in the sides of thedrawhead 0, and thus hinges the couplingpin D inplace.

To one end of the cross-pin E is attached, or upon it is formed, a crank-arm, F, to the outer end of which is attached the end of the chain G. The chain G is also attached to the end of an arm, H, formed upon or attached to the inner end ofa rod, I, which works and slides in bearings J, attached to the end of the carbody A. To the outer end of the rod I is attached, or upon it is formed, a crank-arm, K, for convenience in turning the rod I to raise and lower the coupling-piuD to uncouple and couple the cars. With this construction, when the two cars are run together the end of the coupling --link L, attached to one car, will strike, raise, and pass the coupling-pin D of the other car, which coupling-pin D, as soon as the end of the link L has passed it, will drop down through the said link, and thus couple the cars automatically. With this construction, also, when the rod I has been turned to raise the coupling-pin D, by sliding the said rod inward the crank-arm K will rest against the car-body A, and thus lock the couplingpin D in a raised position, so that the cars can be drawn apart and can be run together without coupling when desired.

To the end of the arm H is attached the end of a chain or rod, M, which may be a continuation of the chain G, and which passes through a bushing, N, in a hole in the top of the car, and is attached to a lever, O, or has a handle formed upon or attached to it. The lever 0 is pivoted to the top of the car- With this construction, by drawing the chain or rod M up- Ward the rod I will be turned to raise the coupling-pin D, and by reaching over, taking hold of the chain M, below the top of the car, and giving it a pull to one side the rod I will slide in its bearings and lock or unlock the coup ling-pin.

The cross-pin E is protected by a guard or shoe, P, placed in the upper part of the interior of the draw-head O, and secured in place by a bolt, Q, passing through its inner end and through the upper side of the said draw head. The forward end of the guard I is grooved upon its upper side to receive the cross-pin E, and is rounded or beveled upon its lower side, so that the end of the entering link L will pass it readily. The guard P is slotted, as shown in Figs. 4 and 5, to receive the coupling-pi n 1) when turned up. The hole in the top of the drawhead (J is covered by a cap-plate, R, which is secured in place by the bolt Q, that holds the guard P. The eap plate is designed to prevent rain and sleet from entering the draw-head O through the hole in its upper side.

Having thus described our invention, we claim as new and desire to secure by Letters Patent l. A car-coupling constructed substantially as herein shown and described, and consisting of the draw-head O, the hinged couplingpin I), the cross-pin E, having crank-arm F, the chain G, the rod I, having arins HK, the guard P, and the cap-plate R, as set forth.

2. In a car-coupling, the combination, with the draw-head (J, the hinged coupling-pin D, and the hinging cross-pin E, having crankarm 1 of the chain G and rod I, having arms H K, substantially as herein shown and described, whereby the coupling-pin can be readily raised and can be locked in a raised position, as set forth.

3. In a car-coupling the combination, with the draw-head (J, the hinged coupling-pin D. and the hinging cross-pin E, of the guard P and its bolt Q, substantially as herein shown and described, whereby the said cross-pin will be protected from the entering link, as set forth.
